HARRY C. HORNISH, OF CHICAGO, ILLINOIS, ASSIGNOR TO ALFRED S. CLARK AND CHARLES F. DENNHARDT, CHICAGO, ILLINOIS.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 792,519, dated June 13, 1905. Application filed May 15, 1903. Serial No. 157,199.

To (0Z6 whom, it may concern:

Be it known that I, HARRY C. HoRNIsH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vapor-Burners, of which the following is a specification.

My invention relates to vapor-burners; and it consists in the several features of improvement as hereinafter described in connection with the accompanying drawings and more particularly pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specification and in which the same reference characters designate the same parts in all of the views, Figure 1 is a central vertical sectional view of a burner embodying the features of my invention. Fig. 2 is a sectional view on the line 2 2 of Fig. 1 looking in the direction of the arrow. Fig. 3 is a bottom plan view of the baseplate of the burner, showing the cut-off for the mixing-passage in its position when the burner is lighted. Fig. 4 is a View similar to Fig. 3, but showing the cut-off in position when gas is generated to light the burner. Fig. 5 is a detail sectional view of the burner, showing the manner of mounting the cleaningtubes. Fig. 6 is a broken sectional view on the line 6 6 of Fig. 5 with the vertical cleaning-tube partly removed, the view being taken in the direction of the arrow; and Fig. 7 is an elevation of the longitudinal cleaning-tube.

Referring to the parts by reference characters, the numeral 1 denotes a generating chamber or retort that is substantially annular in outline and is provided with downwardly-projecting tubes 2 and 3, cast integrally therewith at opposite points and with which the oil-supply pipe 4 and the gasdis char e pipe 5, respectively, connect. The oilsupply pipe 4 is connected to the tube 2 in any suitable manner and preferably by means of the T-shaped head 6, having cross-passages connecting, respectively, with the oilpipe 4 and the tube 2, the passage to the tube 2 eing closed at its opposite end by a suitable cap, with which may be associated an annular washer of asbestos or other suitable material. The gas-discharge pipe 5 leads inwardly to the center of the retort by means of .the longitudinal leg or branch 7, which is closed by a suitable plug 8 and is provided with a gas jet or exit 9, which is controlled by an ordinary needle-valve 10.

The tubes 2 and 3 form convenient sup ports for a base-plate or deflecting-plate 11, which preferably is cast integrally with the tubes by means of suitable connecting-webs 12. The retort is also provided With a pair of downwardlyprojecting oppositely disposed posts 13 and 14, formed integrally with the retort and with the base-plate and arranged intermediate the tubes 2 and 3, as shown in Fig. 2. The plate 11 is provided with a central mixing-passage 15, preferably formed in a slightly-thickened portion of the plate and in line with the gas-exit 9. The plate 11 is provided with a series of curved deflecting-flanges 16, which are vertically disposed and are arranged at or near the edge of the plate and have intermediate openings or passages 17, as shown in Figs. 1 and 2. The deflectors 16 direct the flame upwardly to cause it to impinge on the spreader 18, while the intermediate openings 17 ermit portions of the flame to pass laterafiy beneath the ring 1 and against the tubes 2 and 3 and the posts 13 14 to keep all of these parts properly heated. The deflectors adjacent to the tubes 2 and 3 are provided with beveled or rounded edges or ends in order to insure the direction of the flame against these tubes. The arrangement and disposition of the deflectors are clearly shown in Figs. 1 and 2.

The spreader 18 is in the form of an inverted dish, as shown in Fig. 1, and is provided with any suitable means to seat upon the retort, as legs 19.- It is also provided with a plurality of slits or openings 20, which preferably are four in number, arranged at equal distances around its edge or periphery to permit the passage of portions of the flame.

The burner is provided with a cut-off consisting of a plate 21, adapted to slide or reciprocate over the bottom face of the baseplate 11 in any suitable guides. For this purpose I have provided a pair of downwardly-projecting headed lugs or screws 22, secured in the posts 13 and 14 and adapted to enter elongated slots 23 in the valve or cutoff. The cut-off is provided with lateral lugs or rests 24 to steady it upon the under side of the base-plate and prevent its being displaced. The cut-off is also provided with a central body 25, that is deflected downwardly out of the general horizontal. plane of the plate and which is provided with a mixing and guiding tube 26, that is adapted to register with the exit 9 and the passage when the cutoff or valve is at the limit of its movement in one direction, as shown in Figs. 1 and By this construction the upper end of the tube 26 terminates short of the plate 11, so as to provide an air-inlet between the passage and the tube in addition to that at the lower end of the tube, with the result that a more intense blue flame is secured. The body of the cuto'l'l' is provided with an auxiliary mixing-tube 27, which is offset lateral to the tube 26, the two tubes being in line across the body and being formed in the body of the slide or cut-off. The tube 27 opens below and in line with the under surface of the plate 21 and is employed when gas is generated to light the burner, at which time the cut-off is shifted to the position of Fig. 4, whereby the portion of the plate above the auxiliary tube 27 forms a closure for the passage 15 and the tube 27 is in alinement with the jet 9. In this position of the slide or cut off vapor from the jet 9 impinges on the lower surface of the plate 21, and in order to prevent any oil from running 011 the end of the cut-off I provide the latter with a defleeting-rib 28, which causes any oil that may be deposited 011 the slide to fall into a suitable drip-pan 29. When gas is generated and it is desired to light the burner, the cut-elf is thrown to the position of Figs. 1 and 3 to bring the mixing-tube 26 in register with the jet 9 and passage 15, and the gas and air carry through and mix within the tube 26 and passage 15 to the chamber formed between the base-plate 11 and the cap or spreader 18. It is obvious that the cutofi' may be reversed in position, so as to afford either a right or a left hand burner.

The drip-pan 29 is supported in any suitable manner and preferably by means of a vertical and doumwardly-projecting leg 30 on the under side of the longitudinal branch 7 of the gas-discharge pipe, through which the valve 10 passes and with which it has threaded connection for adjustment. The leg is exteriorly screw-threaded to receive a suitable screw-nut 31, which holds the drip-pan securely in place, and a stuffing or packing ring 32 for the valve 10.

The bore of the feed-tube 2 and the vertical passage of the head 6 are in alinement and are adapted to receive a hollow cleaningtube 33, which fills the passage and extends therein to the retort or gcnerating-chamber, having an opening in register with the supplypipe 4. The lower end of the head is closed. by a cap 35, so that the cleaning-tube 33 may be removed when it is desired to clean the burner, the tube being provided with a hole 36 to receive a suitable pin for withdrawing the same when the cap is removed. The bore of the tube 3 and discharge-pipe 5 are similarly provided with a hollow cleaning tube 37, which passes through an annular projection on the drip-pan 29 in line with the bore of the pipe 5 and provided with a removable closing-cap 38. The tube 36 has a hole 39 for the same purpose as the hole in the tube 33 and a lateral exit or passage 40 in register with the bore of the branch 7. The bore of the vertical pipe 5 is somewhat less in diameter than that of the longitudinal branch 7, and the latter extends somewhat beyond and outside the pipe 5, where it is closed by a removable cap 41. The bore of the branch 7 is provided with a hollow cleaning-tube 42, removable therefrom when the cap 41 is unscrewed by a pin or other tool en gaging the hole 43 therein. The tube 42 is provided with a transverse passage 44, adapted to aline with the bore of the pipe 5 when 5 the tube 42 is in position within the branch 7 and through which the tube 37 is free to pass, the arrangement being shown in Fig. 6. The inner end of the tube 42 is split by means of the elongated opposite slots 45, whereby it passes freely over the projecting end of the valve 1.0. When it is desired to clean the pipes 5 and 7, the tube 37 is first withdrawn, and the tube 42 may then be also withdrawn. The passage 40 of the tube 37 communicates with the interior of the tube 42 when the parts are assembled.
